To all whom t may concern;

Be it known that we, CHARms P. SoHAErnR and ROBERT M. BROWN, citizens of the United States, both residing certain new and useful Im- Construction Ties; and we declare the following to be a full, exact description of the invention,

have invented provements in. do hereb clear, an

such as will enableot'hers skilled in the art -tures, and particularly it appertains to make and use the or the like having an outside veneer of brick,

method for binding structural elements 0 ing blocks,

tile, cut stone or other suitable building blocks.

One ofthe principal objects of the invention is the provislon ofv a, means and to a surface of concrete or the like. Other objects are to tie a veneering of brick or the like to a main building wall, ceiling or Hoor of concrete or the like, in a strong, simple and eicient manner; to facilitate erectlon of structures of the character mentioned; toimprove the means of attachment; to avoid the necessit of using special forms .of tile, bricks orot er buildand otherwise to simplify and improve the building operations of building structures.

The invention consists in the vcombination of elements and details of construction hereinafter more fully described, illustrated in the accompanying drawings, and defined in the appended claims.

In the drawings, in which is' illustrated an improved embodiment of the invention:

Figure l is a fragmentary elevation of a wall of concrete or the like, after the form has been removed, a portion of an outer covering of veneer Wall being shown part- Way completed, and adapted to be attached thereto in accordance with the principles of this invention.

4Figure 2 represents a horizontal on the line 2-2 of Figure 1. y

Figure 3 is a side elevation of a key strip constituting one of the elements for anchoring the outer covering of veneer or blocks to the main elements of a wall, with the cross strip, shown in section.

. at Chicago, in' the county of` Cook and State of Illinois,

Awana ILLINOIS.

In the drawings:

The reference numeral l indicates as a whole the main portion of a building wall, and 2 represents columns or other massive vand strong elements of the wall. These columns are intended to o'r similar material. layer of brick, tile or at 3. This facing layer must be anchored to the main wall structure, as it is relatively thin, being constructed as in the example shown by -a single tier of'blocks.

In order to tie the veneer or facing wall to the main wall structure, means about to be described are provided. Molded perpendicularly in the concrete columns or other A faclng or veneer ele-ments 2 are vertical grooves 4f, which are dove-tailed in cross section or otherwise formed wider at their bottoms than at the exterior openings thereof. These grooves, sometimes known as undercuts, are here designated dove-tailed grooves, and may be 0f any desired form,-so long as their bottoms are wider than the entrances thereto. In order to strengthen these grooves, besides forming them,r they are lined with dovetailed channel members of metal, as indicated at 5. The said members 5 are intended tobe molded in' the concrete with their flanges 6 embedded flush' with the surface of the elements 2. The said dovetailed grooves thus formed, extend continuously throughout the extent intended t0 be concealedv by theveneer orfacing wall. As the facing wa1l3 rises, it will be anchored to the elements 2 by ykey strips 7. Said key strips are preferably made of fiat metal, each havingone end provided with a dovetailed tongue adapted to approximately ll the groove in the channel 5 when the' said key strip intersecting` the axis of the groove.

` In the form shown, the key strips 7 are provided with shoulders at 9, which engage .the surfaces of the Hush flanges 6 of the channel members. It is apparent that these key members 7 may be ad] usted freely in the grooves, that they may be inserted edgewise in the groove and turned to a horizontal position, in which position they cannot be pulled out ofthe grooves. The ends of the key strips 7 opposite the tongues 8 are intended to overlie the course of bricks 'be made of concrete the like is illustrated or other building blocks 3, and to be placed thereon. The said key strips may be made of an length desired in conformity with the thickness of the veneerwall and its roximity to the main elements of the wal s 1 and 2. Adjacent the outer ends of each key strip 7 is provided a loop 10 which ma be formed in any manner thereon, but which is preferably struck up from the metal of the key strips i, as illustrated at Figure 3 in the drawings.l This loop 10 is, of

course, made in the usual manner by slitting the strip 7 a length equal to the width desired for the loop and pressing the portion between the strips out of the plane of the 1 strip. The longitudinal strips 11 are eX of the key strips 7. The tie strips 11 and the key strips 7 being made as shown, of flat relatively thin, although tough and strong metal, do not occupy any great height, but

lie flat upon a course of bricks, and may be i imbedded in a laver of cement or mortar between, upon which they rest and the courses im osed above.

It will e understood that the illustrations are somewhat diagrammatic, and simply for the purpose of clearly illustrating the invention. Such a number of key strips 7 will be used as will firmly anchor the facing wall to the main structure. The key strips and tie strips may be inserted at any suitable distance apart as may be found necessary. As has been before pointed out, they may be anchored to the building at any point, since the key strips 7 are free to be moved along the grooves and channels 4 and 5. No special form of building block is rcquired in order to anchor the keys, the ordinary rectangular brick being preferably adapted to be secured in accordance with this improvement.

We are aware that many changes maybe made, and numerous details of construction varied throughout a wide range withoutde-` parting from the rinciples of this invem tion, and we, there ore, iting the patent granted hereon otherwise than as necessitated b v the prior art.

What we claim and desire to secure by Letters Patent of the United, States is:

1. In a building structure, a main wall element having dove-tail grooves, having in cross section a wider interior than entrance,

2. In a building structure, a main wall element having dove-tail grooves, having openings narrower than the interior, a veneer of building blocks, key strips having one end'dove-tailed to fit the grooves, the other ends of said key strips overlying a course of blocks, and tie strip sections having overlapped ends `secured to the key strips at right angles to them and overlying said course.

3. In a building structure, a main wall element of cementitious material having metallic channel members provided with a dove-tailed groorfe embedded in one face, a veneer of building blocks, key strips having one end dove-tailed to fit the channel members, the other ends of said key strips overlying a course of blocks, and adapted to be embedded. in a layer of cement between courses.
